Frogman, I checked those names and cuts on 'you tube'; of course I had Herbie's album, I was into fusion at the time. I'll bet Rok had it as well, "Fusion" was a good idea at the time. I found some bright yellow, bell bottomed, double knit slacks with three inch cuffs, in the back of my closet a long time ago; since the waist was way too small, they could not have been mine, but the wife said she had no gentleman friends over who left their slacks, so maybe they were mine; if so, they must have been "a good idea at the time".
Enjoy the music.
